These baseball apps a hit

After a long snowy winter, the only white that baseball fans want to see on a grass field is the line that separates fair territory from foul. As the 2015 season revs up these apps can add to your viewing enjoyment or help take you out to the ballgame.

MLB.com At Bat (iOS, Android, Kindle): This official app from Major League Baseball features a complete redesign for the 2015 season, which will be especially noticeable for Android users running Lollipop. At Bat also supports the Apple Watch, so users of the much-anticipated wearable device can see scores with the flick of a wrist. While the app has some free features, you will need a subscription to access live game audio ($2.99 a month). To get live streaming video through the app, you have to subscribe to MLB.TV Premium ($24.99 a month).

MLB Preplay (iOS, Android; free): Anyone can predict what will happen in a replay, but making a right prediction before the play occurs is trickier. With this app you try to outguess other players about what will happen during each at bat, inning or game. The better your predictions, the more points you score.

Home Run Derby (iOS, Android; free): This app is typically updated during the season when the All-Star game approaches, but until then it is still fun to play using real players from 2014. The goal is, obviously, to hit as many home runs as possible. As you progress, you unlock features that make hitting homers easier. You can also purchase power boosts as in-app purchases. The graphics are stunning, but the arcade-type play is hard to master.
